Abstract
During the period from January 2005 till December 2005, a total of 240 Common carps (Cyprinus carpio) from Technical Institute of AL–Mussayab fish farm were inspected for ectoparasites. The following parasites and their percentage incidences of infection and Mean intensity of infection were recorded : Ichthyophthirius multifiliis (%28.3, 10.5), Trichodina domerguei (%18.7, 11) , T. cottidarum (%21.2, 10.9), T. nigrs (%12, 7.3), Glossatella amoebae (%11.2, 4), Apiosoma pisciola (% 16.2, 5.3), Dactylogyrus arcutus (% 7.5, 18), D. Minutus (%1.6, 8.7), D. Achamerowi (% 2.5, 10.3), D. extensus (% 34.3, 6.2), D. solidus (% 11.6, 7.0), D. lipochina (% 5, 8.5), D. amurensis (%2.9, 5.4), D. carassus (% 12.9, 4.6), Gyrodactylus elegans (%3.7, 5.7), Ergasilus sieboldi (%11.8, 7.8) and Lernaea cyprinacea (% 9.5, 6.4). The study revealed abundance of the parasites, which have direct life cycles to occurrence of specific species of parasites with low percentage incidence and mean intensity of infection. Finally the study revealed that some fishes are highly host specific to some parasite in general.
